perf_hooks is available since nodejs v8.5.

Check your nodejs version by node -v.

My code had:

if (typeof performance === 'undefined') {
  // Older Node.js
  globals.performance = require('perf_hooks').performance;
} else {
  // Browser.
  globals.performance = performance;
}

to work around: https://github./nodejs/node/issues/28635 that hadn't been solved.

Since in that case the browser is taken care of trivially by the exposed global, I just hacked it to:

  globals.performance = eval('require')('perf_hooks').performance;

which makes webpack incapable of seeing the dependency as desired, as mentioned at: How can I make webpack skip a require

Tested on react-scripts 4.0.3.
